Crystal structure models are used by material science professors to help explain how structure influences properties of various materials. Some models come in self assembly kits like the molymod line [2] or molecular model company [3] that range 20-40 Euros, but more detailed models can run hundreds of Euros [4]. Some can even be thousands of euros - particularly for large scale or complex models. Ideally, anyone interested in material science could print these structures in any size or format for a few pennies.
